TYPEWRITING MACHINE.

Application filed November 12, 1924.

'This invention relates to special paperfeeding devices for typewritingmachines designed to facilitate the writing of bills or the like, andsimultaneously recording them in a manner commonly known as condensedbilling, and is in the nature of an improvement on the mechanismdisclosed in the co-pending application of Harry H. Vickers, Serial No.543,971, filed March 15, 1922 1" (now Patent No. 1,569,900, datedJanuary In preparing a typewritten pay-roll or record-sheet, it has beenfound desirable to write said sheet at the same time that the payecsindividualreceipt and pay envelope are written, thus avoiding errorsthat might otherwise occur, and also saving time. A record-sheet usuallycomprises a printed form subdivided by vertical and horizontal linesinto a number of separate blocks or spaces into which may be written thenames of employees and data relative to their pay.

In cases where employees are paid on an hourly basis, it is customary toprint by the use of metal stencils, in vertically-arranged blocksadjacent the left margin of the record-sheet, the names of theemployees, one name appearing at approximately the middle of each block.The rate of hourly pay F corresponding to each employee is stenciledbeneath his name and spaced so as to occupy a position closely adjacentthe lower marginal line of its enclosing block. In making out such apay-roll, the typist is furnished with certain data relative to each ofthe employees, and types said data in an appropriate block or columnusually to the right of the block containing the employees name andrate. An individual reecipt blank and a pay envelope, each having anoverlying carbon, are placed beneath the pay-roll or record-sheet andare typed simultaneous ly therewith. It is necessary while typing suchdata upon the record-sheet and associated papers to first advance theplaten so as to throw the record-sheet upwardly a sufiicient distance tobring the stenciled hourly rate of an employee above the printing lineto enable said rate to be observed. This is done so that the typist maycompare and check up said stenciled rate with certain rate Serial No.749,359.

data furnished by the foreman, and thus eliminate any possibility ofmistake or recti fy any discrepancies which may appear.

After aving observed the stenciled rate and properly checked the samewith the information furnish-ed her, the typist brings the name of theemployee appearing on the record sheet to the printing field and thenstarts typing in the columns to the right of said name. These columnsusually include the number of hours worked, the earnings, deductions andthe total amount to be paid. After having typed the data relating to oneof the employees, the platen is next turned so as to bring the rate ofthe next employee into View, a new receipt blank and pay envelope areinserted, and, after observing the new rate and having properly checkedthe same as above outlined, the platen is turned in the oppositedirection so as to bring the new employees name to the printing line.

One of the features of the present invention is the provision of meanswhereby the platen maybe quickly rotated to advance the initial typingline of a work-sheet beyond the printing field to enable informationappearing beneath said initial typing line to be observed, and then uponreversal of the platen to quickly bring said line to the print- 8!) ingfield for typing.

Another feature of the invention is the provision of means for gagingthe ends of additional work-sheets or the like, which are insertedbehind the record-sheet, and then run to the printing line to besimultaneously typed with said record-sheet.

Other features and advantages will hereinafter appear.

In the accompanying drawings, A no Figure 1 is a side elevation of theplatenframe of a typewriting machine, showing my invention appliedthereto.

Figure 8 is a view of an employees in dividual receipt blank.

The usual platen 10 is rotatably mounted by means of an axle 11 in aplaten-frame 12, which includes a work-table 13 and feedrolls 14 and 15,the latter being equipped with suitable throw-off mechanism (not shown)for releasing the rolls from the platen when required. A wheel 16,having teeth or notches 1?, "is fixed to the axle 11 adjacent one end ofthe machine, and a crank 18 is "mounted upon the axle and is swingablein an are adjacent the wheel 16. A housing 19 in the form of an annularrim surrounds the wheel 16, and is held against movement by means of atierod 20 fixed at one end 21 to the housing 19, and at the other end 22'to a "portion of the platen-frame 12. The crank 18 has an offsetportion 23 for the reception of a pin 21, which provides a pivotalmounting for a dog 25, the end of the latter being formed with a tooth26 for engagement with the notches 17 of the wheel 16. As the crank 18is thrown forwardly and rearwardly, the dog operates 'to turn the wheel16, and thereby rotates the platen forwardly and rear wardly tosimultaneously lower a recordsheet, a receipt blank andan envelope, orto raise them with relation to the printing fi'eld. In handling apayroll or record-sheet, it is customary to advance the same through aregularly-space-t distance after certain data relative to one payee istyped, so that "the rate of pay of the succeeding payee may be observedand the pay envelope and individual receipt blank removed and new onesintroduced. Mechanism is therefor provided for permitting the platen tobe turned through a full stroke during a rearward 'nioveinent of thecrank "18 tocarry the printing line of the record-sheet above theprinting field, whereas a forward movement of said crank results in ashorter movement of the platen in the opposite directionto bring saidrecord-sheet down "to the printing field for typing.

In order to accomplish this result, there is provided adjacent the topof the housing 19 suitable latch mechanismincluding a pair of annularrecesses 27 and 28 into which are received a pair of disk-lik 'e'turningmemb'er's29 and 30, which move about their azie's within said annularrecesses and are returned to normal position by means of coil sprlngs 31and 32, in a manner similar to the mechanism disclosed in the patent toW. H. Woodford, No. 923,7d9, granted June 1, 1909.

The disk member 29 includes a latch 33 and the disk member includes alatch 34:- The dog 25 has a pin 35 which normally rides around theinterior of the housing 19 against an annular surface 36.

Attention is directed to Figure 3, which ilhistrates the method ofintroducing work into the machine. S represents a recordsheet orpay-roll which has been introduced into the machine along the rearpaper-table 13 after having first thrown the crank 18 to the rear andreleased the feed-rolls 14 and 15, so as to permit the record-sheet tobe "introduced around the platen to bring an employees. rate 37 to theprinting field to be observed.

Upon inspection of Figure '6 it will be seen that the record-sheet S mayinclude ver'tically-arranged blocks 1, each of which contains anemployees name 2 spaced above his rate 37, and also a'number of blocks3, 4e, 5 and 6, which may have respectively typed therein hours,earnings, deductions and amounts to be paid. With the record-sheet S inthis position, an individual receipt blank R and pay envelope E, eachhaving blocks or spaces similar to the blocks 3, 4;, 5 and 6 of therecord-sheet S, are interleaved with carbons R and E "and placed behindsaid record-sheet, and then gaged against a gage 38, which may be fixedupon the platenframe, as clearly illustrated in Figure 3. After havingobserved the rate 37,-the typ'ist throws the crank 18 forwardly 'to movethe sheet S, the receipt blank R and pay envelope E simultaneously tothe printing field, that is, to bring the name 2 of the'record-shect'down to typing position, so that the blocks 3, 1, 5 and 6to the right thereof may be typed in line with said name.

During the forward movement of the crank 18,the pin 35 rides against theannular surface 36 of the housing 19, ther by holding the dog 25 inengagement with the notched wheel 16 until the pin 35 reaches adepending lip 33 of the latch 33 (see Figure 1). The dog 25 then ridcsupover the lip 33, thence over the body of the latch 33 and thence into arecess'39, thereby withdrawingthe tooth 26 o f'the dog 25 from thenotches 17 of said wheel. As the crank 18 continues in its movement thepin 35 rides off of the latch 33, onto a bridge portion 4.0 forming aportion of the housing '19 and thenonto the latch 34. The continuedmovement of'the crank 18causes the pin 35 tojbe deflected from therecess '39, and causes the latch 3-tto be turned axially against thetension of its *spring 32 to permit 'the pin 35 to ride out of therecess 39 and drop to position to re-engage the teeth of the wheel 16,as clearly illustrated inthe dot-and-da'sh lines of Figure 2. The platenis thus moved another short distance until the edge of the crank 18 isstopped against a pin ail. After typing all of the data necessary to bewrit ten relative to this particular employee, the crank 18 is movedrearwardly to a position indicated in dotted lines in Figure 1. Duringthis movement the pin 35 rides beneath the latch and causes the tooth ofthe dog 25 to remain in engagen'ient with the teeth of the wheellG forthe full return stroke of the crank, and it will be noted, that as thepin 35 comes in contact with thedepending lip 83 of the latch 33, thepin 35 cams thereagainst and causes the disk 29 to revolve about itsaxis against the tension of its spring 31 suificiently to allow the pin35 to pass freely beyond said lip and to position against the annularsurface 36. (See full lines of Figure 2.) The rearward movement of thecrank 18 is stopped by a pin 42. The record-sheet S has now beenadvanced to bring the next rate to view and also to permit the envelopeE and receipt R, which have been typed upon, to be removed from themachine, so that new ones may be introduced and brought to positionagainst the gage 38. A pap-ergui.de 43 and a paperfinger a l may be usedto hold the sheet S, the recei 3t blank R and envelope E in positionwhile being written upon, and a wing scale 87 may also be used. Thefinger 44 functions a support for the sheet S when the same is thrownforwardly of the machine to permit easy access to the work beingintroduced against the gage 38.

It will be seen that by use of the above described mechanism work-sheetsmay be readily introduced into the machine and certain portions thereofquickly brought to View for observation, and then quickly run toposition to be typed upon, thus saving much time in typing thischaracter of work, and adding greatly to the ease and facility withwhich it may be handled.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.
